One of the things driving the ever-increasing weight of new vehicles is all the power accessories that we have. We now have power windows, power locks, power seats, power adjustable mirrors and on and on. Every one of those accessories requires an electrical actuator of some kind to operate and all those actuators add up to a lot of weight. Supplier Robert Bosch has introduced new electric drive actuators with twenty percent less weight and quieter operation than the previous generation. If new motors like these can be applied across the board on new vehicles, they'll save a significant amount of weight.
